Stents versus bypass surgery: 3-year mortality risk of patients with coronary interventions aged 50+ in Germany.

Objectives: Due to demographic aging, the prevalence of coronary artery disease (CAD) is expected to increase in the future, resulting in a growing demand for stent and bypass interventions. This study aims to investigate the mortality risk of patients following conventional coronary artery bypass grafting (CABG) or endovascular procedure by the implantation of bare-metal stents (BMS) or drug-eluting stents (DES).

Methods: Based on a random sample of 250,000 members of Germany's largest health insurance 'Allgemeine Ortskrankenkassen' (AOK) from 2004 to 2015, incident CAD patients were analyzed by Cox Proportional-Hazard models.

Progression to severe visual impairment and blindness in POAG patients: pace and risk factors-a cohort study using German health claims data.

Objective: Glaucoma is a leading cause of severe visual impairment and blindness (SVI/B) worldwide. Hence, it is of utmost importance to explore relevant risk factors and study the pace of progression to SVI/B.

Methods And Analysis: We used a random sample of 250 000 persons from administrative individual-level health records of the Allgemeine Ortskrankenkassen between 2004 and 2015.
